Upchuck- Looking a little worse for wear this shag was just a snack for this hungry Murray cod.
Did you see that? Fishing mate Gus Storer pointed to an eruption of water not twenty meters away. Amidst the chaos, a parent duck is frantically trying to protect her young as the water around her hapless youngsters explodes again. Unseen, the menace from below makes a final rush. This time three of the small ducklings are sucked into the abyss. This ferocious assault could be likened to that of a shark cruising the ocean currents in a life and death struggle to survive. However this spectacle is played out a little closer to home on the tranquil calm of the Murray River. The unseen foe in question none other than a giant Murray cod. King of its domain, all who fit in its bucket-sized gob are on the menu. As luck would have it, on this day the female black duck managed to make the safety of the bank with several of her clutch still intact. Small consolation for those who ended up as lunch, but not all who meet the mighty Murray cod on their home turf get away so lightly.
Stomach contents of larger fish over the years have shown that they are not only a veracious predator they are also quite the scavenger. And while I have seen many strange things regurgitated by these giant fish, this season has been a real revelation as to what sized prey they will actuality tackle. It’s around this time every year when large flocks of cormorants push schools of bony bream to the surface in a feeding frenzy. It’s a free for all joined in by pelicans gulls and whistling kites. Under the waters surface, the mass of large black birds ravenously plunder the hapless fish. Not far below, unbeknownst to these birds another predator has honed in on the action. With cunning calm, it lies in wait as the moving mass draws closer. Amidst the fleeing frenzy the cormorants work with grace, focused on their busy meal they are unaware of the giant closing in. An explosion of power launches from the depths. Mouth ablaze, it inhales not the baitfish but one of their tormentors; the large black cormorant disappears in an instant. The rest of the flock work on oblivious to the fact their numbers are now one less; the cod itself retreats to its haunt to lie in wait for that next feathery meal.
Twice now I have seen large cod regurgitate one of these birds in the boat. While the smell was a little stifling at the time, it gives a great insight as to just what these fish are capable of consuming. The underwater struggle of life and death puts all that dwell within its realm on the menu of the rivers number one predator, the mighty Murray Cod.
